Default Re: Custom Frame For Thumper Motor

I too have been thinking about using a Thumper and would really like to thank you and the pioneers here for blazing the trail!

In regards to the oil blow by issue you solved so well in post #89 do you think this idea could also work?

There's already a plug at the end of the mounting flange so this would be a pretty easy fix.

But perhaps there would still need to be a vent incorporated?
